Making Enough
Most recipes give guidelines as to how much a single batch will produce. But what if you want more? It seems too time consuming to mix up another batch. What if the recipe makes only one dozen cupcakes and you need three dozen? Clearly, three dozen is three times more than 1 dozen, so we can multiply all the ingredients by three to make a larger batch.
Being Creative
Sometimes, we may not have all the ingredients to make a recipe, but we may have something we can fittingly substitute. How does this affect the measurement amounts in the recipe? For example, let’s imagine we are making Rice Krispie treats. The recipe calls for 32 large marshmallows, but we only have miniature marshmallows. We can still use the small marshmallows, but we will need to estimate how many mini marshmallows would make one large marshmallow, and multiply that number by 32.
Weight
Weight often affects cooking time. Consider the following hypothetical situation: we are cooking an 8 pound turkey for Christmas dinner. If the turkey needs to thaw in the refrigerator for 24 hours, per 5 pounds, we need to take the turkey out of the freezer in advance. We can use a proportional relation to help us decide how early to thaw the turkey.
Cost
We also use math when cooking and baking to estimate the cost of a certain dish. We can understand that cheesecake is more expensive to make than a batch of cookies, particularly when people buy ingredients such as flour, sugar, and butter in bulk and cream cheese is more expensive. When comparing recipes, it may be beneficial to estimate the cost of each recipe.
Conversions
Most ranges have dials that display the cooking temperature of the oven. In North America, most of these temperatures are written in Fahrenheit. In Canada, recipe and oven temperatures are often presented in degrees Celsius. It is important then to understand how to convert a Fahrenheit temperature to an appropriate Celsius temperature.
We also use conversions when we bake or cook to convert sizes and amounts. Many recipes are written in imperial units (teaspoon, tablespoons, and cups).

how algebra is used in cooking
Math is in every kitchen, on every recipe card, and at each holiday gathering. The mathematics of cooking often goes unnoticed, but in reality, there is a large quantity of math skills involved in cooking and baking.
Math in Cooking
Mathematical skills are used quite frequently when baking and cooking. It can be very helpful to understand how math affects the quality of culinary in order to make the most delicious meals and treats.
